Abstract : This report describes the results of computer simulations of optical devices which contain birefringent elements. The physics of pulse propagation in birefringent fiber is summarized first. The behavior of pulses in birefringent fiber amplifiers is examined. These pulses will break up under high amplification. This behavior is shown in the simulations. Simulations of the Nonlinear Optical Loop Mirror are shown. The differences between the behavior of these devices with pulsed and nonpulsed inputs are discussed, and approximate analytical models are derived. The effect of changing polarization controller settings is examined extensively. A fiber ring laser mode locked with a Nonlinear Optical Loop Mirror is studied. It is shown that the cavity length can be increased greatly if the dispersion of the fiber in the amplifier and in the loop mirror is balanced so that the pulse is nearly a soliton in both elements.
